AIR-LAP1522 power via eth, data via FO. Possible?

Hi all. I need do place AP1522 about 300 meters from distribution cabinet. As a data link i will use SM FO cable. I dont have power supply where AP is, but I have 1 pair of copper cable (20AWG). I would like to use power injector on the cabinet side, connect it to cable and plugged to eth port on the AP side. And my question is: is it possible? I'm afraid that ethernet port is off when optic port is enabled so power will be switched off.
Regards
Marcin

Marcin,
I believe you can use multiple power sources when powering up the mesh AP's. per the doc, that's what it states. Search the forum as about a few months back, someone did post on the same concern as you have. Maybe you can find the post and reply to see if it worked or not.

Data log directly from Norma 4000 power analyser rather than via Keithley 2700 data logger

Hello fellow LabVIEW users
My Norma 4000 power analyser is connected to my Keithley 2700 data logger from which it logs data via GPIB using the attached VI.
Prior to making this VI I was not aware that the Norma 4000 could also log data values directly using labview which I found in the following LabVIEW post.
http://forums.ni.com/ni/attachments/ni/170/536731/1/LV9.zip
The Keithley logs the values into a *.txt file that can be opened in excel for analysis of the data. There are 7 values that are pulled from the power analyser and 1 from a radiometer and 1 from a temperature sensor. I essentially want the 7 values from the data analyser be directly input into the save file i/o rather than going via the Keithley which it is doing now. Some the signal is lost due to noise etc when going from ADC then DAC. Which is why certain values pulled from the Keithley have been multiplied before being put into file i/o.
Since these are popular instruments of choice I was wondering if anyone can direct me to any links to LabVIEW VIs that have already been made that DIRECTLY logs data values from the Norma 4000 into a *.txt file as in the attached VI. Or point me in the right direction perhaps. The LNOPA01 Getting Started.vi only shows current values. I want the data values to be logged into the *.txt files at certain time intervals with the corresponding signals from the radiometer and temperature sensor.
The Keithley drivers can be found in the following link

Thanks for all the help beforehand.

Hi,
I was not able to find an example that will directly log data from the Norma 4000. I looked at the LNOPA01 Getting Started.vi and it seems like, with a few modifications, you could use this to log data. You would have to open a file, write the collected data to the file, and then close the file. You are already doing something similar to this in the VI you attached.
If you only want to measure data at certain times, you could use a case structure in the while loop and only write to file when a certain condition is met. If this isn't an option for you, could you please elaborate on what difficulties you are seeing?
Thanks,
Paul B.

Nested IPE (In Place Element) usage when accessing Cluster/Array data via DVR

I am sharing data across several VIs and loops via a DVR, and accessing the data via a DVR IPE. The data is a cluster of arrays. The diagram below (VI attached) illustrates the structures invloved, but not the structure of the application.
(The diagram above does not include initialization of the arrays, as it is intended only to illustrate the Cluster1 data type. Array lengths could be 100.)
The DVR (DVR1) is passed to multiple VIs of the application at startup.
Each VI executes loops that either read or write particular elements of each array (fArray1 or fArray2).
I believe the DVR IPE (B1-DVR) provides blocking so that only one task can modify the data (Cluster1) at any time.
Case 1 illustrates how I currently WRITE to array elements. The outer IPE (block B1) is rolled into a VI (not shown) that takes DVR1, Index, and Value as inputs.
Cases 2 - 4 illustrate 3 additional methods that remove one or both of the inner IPEs (B2-Cluster and B3-Array).
Case 2: IPE B3 (Array Index/Replace Elements) is replaced with a non-IPE 'Replace Array Subset'.'
Case 3: IPE B2 (Unbundle / Bundle Elemnts)' is replaced with a non-IPE cluster 'Unbundle'/'Bundle'.
Case 4: removes both B2 and B3.
I implemented case 1 a long time ago. When I had to do the same thing again recently, I did case 4. When I stumbled across my earlier implementation, I was a bit suprised
Which of the 4 cases should take the least time (or resources) to execute? I think case 4 has as few array allocations as any of the other 3.
The attached image did not capture the Buffer Allocation marks, so I marked the ones that differed with a red "B".
I am only interested in differences in how the arrays are handled, so I see no signioficant differences.
Is this one of those cases where LV doesn't need my help?
Incidently, I recently wrote a small app with shared data and decided to try FGVs to share array data. For small arrays, 10^7 iterations, and an FGV based array-element read followed by a element write, the FGV was faster. 1.2us per read/write for FGV vs 3us per r/w for an DVR/IPE based read/write (like above).

Option 1 is a definite no and as far as I know it has been NI's explicit intention to steer clear from it. I believe there's an idea in the IE which asks for this.
I agree that option 2 makes sense, but I don't think it should be something the user specifies. Either LV can detect it automatically or it can't, but I doubt NI would let you have an option which creates the possibility for this kind of bug.
I'm not sure, but the mark as modifier option on the IPES might be the option you're looking for. I know that it exists and I know very roughly what it does, but the documentation for it is very limited and I never actually played around with it, as usually I don't need these kinds of optimizations.
You may well be right that a new option on the IPES is desirable and you should probably add it to the idea exchange.
As for NIWeek, I'm not going this year, so I have no idea what kinds of sessions are around, but it's a great place to find people who know what they're talking about and ask them about it directly. Certain people in LV R&D would probably be ideal for this and if you ask relevant people, you might even get their names. I'm sure buying them a beer would also help to loosen their tounges. If you ask me, this type of interaction is the main value of the conference, not the sessions themselves.

Can we view HR DMS data via PA20/PA30

Dear SAP HR GuruS!
We had a requirement wherein we stored HR Data scanned and stored on
DMS server, we wish to link Employee DMS data to Employee master data
i.e supervisor should be able to view Employee data via PA30/PA20. what
is the way to view employee record ( Stored in DMS Server) ,
I am looking by any mean can be link it to PA20/pa30 to any infotype,
in one of the Tab of employee master data...

Hey,
There is no standard solution, but yoju can use this (see below) to create a object link between HR object and DMS
//Håkan
Adding Other Objects
Purpose
You can also link documents with SAP objects for which no linking is supported in the standard
SAP System.
Prerequisites
In Customizing for the Do
cument Management ,SAP objects that you want to link to document info records, by choosing Control Data ® Maintain key fields.
Process
Program two screens for the following module pools for the SAP object that is to be linked additionally:
u2013 SAPLCV00
u2013 SAPLCVIN
The process logic must be according to that of screen 0204 in program SAPLCV00 and must not be changed.
Create the function moduleOBJECT_CHECK_XXXX (XXXX = name of the SAP object).
If this object can be classified, this function module already exists in the standard system. Otherwise, copy the existing function module OBJECT_CHECK_EQUI (linking of equipment) and change it to suit the new object.
Result
After you have completed the above, documents can be linked with the SAP object that you have added. You define the settings for this in Customizing for the Document Management System (see:
Object Links).

Error trying to extract data via HFM objects

I've written a program to extract selected data from HFM (version 11.1.1.3.500) using the API objects. The program (shown at the bottom of this post) is failing on the 2nd of the following 2 lines:
oOption = oOptions.Item(HSV_DATAEXTRACT_OPT_SCENARIO_SUBSET)
oOption.CurrentValue = lBudgetScenario
where oOption is a data load/extract object previously initialized and lBudgetScenario is the long internal ID for our budget scenario.
The error is usually "COM Exception was unhandled" with a result code of "0x800456c7", but, mysteriously, even with no code changes, it sometimes throws the error "FileNotFoundException was not handled", where it says that it could not load "interop.HSXServerlib or one of its dependencies". The second error occurs even though HSXServer was previously initialized in the program and used in conjunction with the login.
I've carefully traced through the VB.NET 2010 code and find that all relevant objects are instantiated and variables correctly assigned. It also occurred to me that the data load DLLs might have been updated when the 11.1.1.3.50 and 500 patches were applied. For that reason, I removed the references to those DLLs, deleted the interop files in the debug and release folders and copied the server versions of those DLLs to my PC. I then restored the DLL references in Visual Studio which recreated the interops. However, the error still occurs.
The ID I'm using (changed to generic names in the code below) has appropriate security and, for example, can be used to manually extract data for the same POV via the HFM client.
I've removed irrelevant lines from the code and substituted a phony ID, password, server name and application name. The line with the error is preceded by the comment "THE LINE BELOW IS THE ONE THAT FAILS".

End Module

I stumbled upon the solution to my problem. The documentation for extracting data via objects defines member ID variables as Longs. In fact, I've always defined such variables as longs in previous object programs and had no problems. It appears that the datal load/extract "option" property of "Currentvalue" is defined as integer. When I changed all of my member ID items (such as the "lBudgetScenario" variable that was the right-side of the failing assignment statement) to be integers, the program worked.

Is it possible to virtually bypass the battery on a macbook pro (retina 2014) and power the mac directly via AC power?

Is it possible to virtually bypass the battery on a macbook pro (retina 2014) and power the mac directly via AC power?
E.g. Dell allows you to plug the laptop into AC power but prevent battery charging.
Note: I do not want to physically remove the battery.
If there isn't an option on Mac OS, is there anything I can download to bypass the battery when I want?

Thanks for linking me! Wow I had no idea the clock speed would be cut so severely! What a bunch of rubbish, as if the AC won't provide enough power!
I guess the only solution to my question would be an app which virtually disconnects the battery but tricks the mac into thinking the battery is still connected. I'm just surprised Apple haven't yet started to build prisons for the government - considering how well they lock up their software and hardware!

HT4203 My iphone 4S cant connect to internet via cellular data after upgrading to version 6.0.1, please assist

Hi everyone. I recently upgraded my Iphone 4S fromOS ver 5. to ver 6.0.1

Any errors?
What has been tried so far?

How do I add simple text to a photo? For example, if I took a photo of a chalk board and wanted to add a date via Lightroom making it look like it was written on the chalk board, how would I do that?

I simply need to know how to do this. Everything online talks about doing this as a watermark feature or during Export only. I need to know how to do this during the Develop stage, if it's possible.
I took a photo of a couple for a pregnancy announcement shoot. We added a chalk board that had the date the birth is to take place written on it, but it didn't show as well when I reviewed the first couple pics. So I erased the chalk board thinking that I could just add the date via Lightroom, but I have been unable to figure it out. Any help would be very much appreciated.

To create a graphic watermark or identity plate for this purpose with a hand written chalk look you would need Photoshop or Elements to create a transparent PNG file so you might as well do the whole thing in one of those programs to start with. You can't do this in the develop stage anyway like you requested.

Calling a new browser window with WD Abap and passing data via POST

Hi there,
does anybody know whether passing data via POST method is possible when opening a new browser window from within a Web Dynpro Component? In my case I use method IF_WD_WINDOW_MANAGER->CREATE_EXTERNAL_WINDOW for opening a new browser window. Now I want to pass a big amount of data which is only possible via POST method. How can I achieve that or is it not considered inside the Web Dynpro Framework?

Error in Release of Network data via BAPI_BUS2002_SET_STATUS

Hi Experts,
I have to release network data via a Custom Report Program, so I am using the STD BAPI , BAPI_BUS2002_SET_STATUS.
The functionality must be similar to the release of Network as in case of transaction CN22 or can also be done via Project Builder(Transaction CJ20N).
we r using the std BAPI as follows :
CALL FUNCTION 'BAPI_BUS2002_SET_STATUS'
    EXPORTING
      number                    = < NETWORK NUMBER >
      set_system_status = 'REL'
    IMPORTING
      return             = c_return
    TABLES
      e_result           = lt_result.
The error is Error in processing. Function was not executed . On further analysis, the Function Module CO_ZR_HEADER_RELEASE is causing the issue , not allowing network header data to be free.
The same functionality works via CN22. Please advice whether there is a need to pass further parameters or anything else.
Awaiting a response..
Regards,
Sonika

Hi,
there are some special requirements for using this BAPI. You need to call BAPI BAPI_PS_INITIALIZATION and BAPI_PS_PRECOMMIT with this BAPI. Check documentation for your BAPI. It's well documented there.
Cheers

Subject: DataField, update underlying data via TOOL, Express
In TOOL code we PasteText() into a DataField, but the underlying data
object does not get updated until the user interacts with the GUI.
That causes problems if we need to use the underlying data object's
value immediately after the paste. How can we:
force an update of the underlying data object and
ensure that the update goes through before our method call returns,
i.e., ensure that if the update is via Forte events, those events
are handled before returning.
The context is a calendar lookup button that pastes into an adjoining
DataField.

Well, I think I have answered my own question, but I will leave it here in case anyone else has the same problem.
So, as far as I have been able to track down, it all went wrong when I was running through the connection wizard.
Under the section titled "Creating the Data Source" is describes how to find your database file and create the appropriate connection string. However, on my version of VS Express 2010 . It offered me a prompts , saying something like, "would you like to
move this database file into the application directory and change the connection string" this sounded very sensible to me, so I said yes.
All proceeded accordingly. And the database file now appeared in the solution explorer.
The app config file said that the connection string was
Data Source=|DataDirectory|\Database1.sdf"
I presumed this would be interpreted correctly by the rest of the app, as it was generated by VS.
But it didn't, what I cannot understand is how no error was generated. And data seemed to pull
into the bound controls.
But I have been testing it for a while now. and it seems that if I manually override the config file with the actual directory where the file exists , then there is not a problem. Data is retained in the file
This is more of a VB.net question, but I couldn't find it in the drop down. I will try and move it there now
Thanks guys for your patience.
p.s. RSingh , the code I posted above did come from the SaveItem_Click event
handler

Lumia 520 "Remote wipe of user data via Internet"

I'm interested in purchasing a Lumia 520 and read on the spec site that it can do "Remote wipe of user data via Internet" (http://www.nokia.com/in-en/phones/phone/lumia-520/specifications/).
Is there any special software that I need to be able to do this (like have it connected to a BlackBerry server in the case of enterprise BlackBerry devices) or is it as simple as stated on (http://www.noknok.tv/2013/05/02/how-to-find-your-lost-nokia-lumia-running-windows-phone-8/) where all you have to do is log into windowsphone.com where you can erase a linked phone?
This phone will be used for business so in case it is lost I need the ability te remote wipe it. Our company currently has a BB server and we all have BB devices, but with BB not doing so well I was thinking of getting a Nokia.
Thanks.
Solved!

Would it matter if the same SIM is installed on the phone? Lets say the 'thief' was able to get into the phone with a different SIM (if the security was not setup correctly) - would the phone be erased based on the SIM that's installed or on the IMEI number of the device?
Thanks
If there's no data connection, windowsphone.com cannot access your phone to send push notifications and if push notifications fail, then it will try to send SMS to your phone.
I just tried to ring my phone after taking out the SIM card, it was connected to wi-fi and I could ring it.

Here's an interesting bit: iTunes will let me restore my iPod touch from backup: it's still running iOS 4.3.3. I figured as much... there's backups showing in the Preferences -> Devices list for both devices (and even my old, long gone iPod touch 2G), but my iPhone (on iOS5) isn't giving me any such option. I remember I had to downgrade before to get the backup restored (something went haywire in the setup assistant, and I couldn't restore a backup from iTunes there)... If it was possible to go to iOS 5.0 rather than 5.0.1 I would just do the same thing again, but iOS 5.0.1 isn't an option. I attached a screenshot. Hopefully Apple can get this nonsense sorted out; I think iOS 5 might be the root of this, somehow.
